ABSTRACT

The present application relates to a rinse-off composition comprising an oil phase and an aqueous surfactant matrix, wherein one or more active agents are dissolved in one or more non-polar, water-immiscible solvents, and the oil phase is dispersed in the aqueous surfactant matrix. The present application also relates to methods of delivering the active agent(s) to a subject in need thereof topically, for example to the skin, the hair, and scalp. The present application also relates to use of the rinse-off compositions to treat and/or prevent topical conditions such as dermatitis and psoriasis. In some embodiments, the rinse-off compositions of the present application are shampoo compositions.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent applicationSer. No. 16/820,128, filed Mar. 16, 2020, which claims the benefit ofpriority from U.S. provisional patent application No. 62/818,366, filedMar. 14, 2019, the contents of each of which are incorporated herein byreference in their entirety.

FIELD

The present application pertains to rinse-off compositions useful, forexample, for the delivery and deposition of active agents, such asactive pharmaceutical ingredients (APIs), in particular hydrophobicAPIs. More specifically, the application is directed to a rinse-offcomposition, such as a shampoo composition, comprising an oil phase andan aqueous surfactant matrix wherein one or more active agents aredissolved in the oil phase, as well as methods and uses thereof fordelivering the one or more active agents to a subject.

INTRODUCTION

Delivery of hydrophobic and poorly soluble APIs in a surfactant-rich andaqueous based composition may be challenging due, for example, to theinstability of such compositions and poor solubility of the API in suchmedia. This problem is accentuated in personal care products such asrinse-off compositions including shampoo, where ideally the product isapplied only for a short amount of time, enough to allow appropriatefoaming and rinsing off, but there is a need to deposit sufficient APIon the hair and skin during product application to permit diffusion ofthe API to the site of pharmacological action.

For users with skin conditions such as dermatitis or psoriasis in theirscalp, the development of an effective API-containing rinse-off deliverysystem such as a shampoo is particularly challenging since many APIssuch as corticosteroids (e.g., clobetasol propionate, halobetasolpropionate) are highly hydrophobic and water-insoluble.

Currently, there exists on the market one shampoo product containingclobetasol propionate, Clobex™ from Galderma, that treats psoriaticlesions in the scalp. However, this composition requires that theshampoo be applied to the scalp and left on for 15 minutes beforelathering and rinsing. This length of time presents a significantinconvenience to the user as the typical shower time in the UnitedStates based upon Environmental Protection Agency (EPA) estimates isabout eight minutes.

U.S. Pat. No. 6,495,498 B2 discloses a shampoo composition comprising awater-soluble silicone agent, a cationic conditioning agent and adetergent for the delivery of benefit agents. However, this patent doesnot disclose the solubilization of active agents in an oil phase.

U.S. Pat. No. 4,835,148 discloses a rinse-off shampoo compositiontargeting skin disorders of the scalp that requires insolubleparticulates of API to come out of suspension upon dilution during hairwash thus depositing onto the scalp. This method of delivery is usuallyineffective for APIs that need to permeate the skin to have therapeuticeffect, since water-insoluble particulates generally do not diffuse tothe site of pharmacological action nor produce pharmacological activity,and must undergo dissolution in sebum in situ before such diffusion andactivity can occur.

U.S. Pat. No. 6,183,757 B1 discloses a rinse-off antimicrobial cleansingcomposition comprising an antimicrobial active, an anionic surfactantand cationic polymers as deposition aids in an aqueous composition.However, this patent fails to teach solubilization of hydrophobic APIsin a water-immiscible oil phase.

There is a need to develop a composition containing a hydrophobic APIfor personal care products, such as shampoo for hair cleansing and otherrinse-off products, that is convenient to use (e.g., short leave-ontime) and allows for deposition of said API onto the skin and hair andsubsequent diffusion to a site at which it exerts its pharmacologicalactivity.

IV. Examples Example 1: Clobex™ Composition Using HBP as Active Agent

A replication of the Clobex formula (replicate of Clobex formulationbased on U.S. Pat. Nos. 7,316,810, 7,700,081 and 8,066,975) with HBPsubstituted for clobetasol propionate (CP) was prepared along with avehicle (HBP replaced by water) to provide benchmarks for subsequentevaluations of prototype rinse-off compositions as shampoo compositions.These contents of these compositions are provided in Table 1.

The inclusion of 10% ethanol in Clobex shampoo would be expected to havea deleterious effect upon the lathering of a shampoo and may causeirritation if left too long on the skin, but is likely incorporated inthe product to help solubilize CP as well as increase the skinabsorption of the drug during the 15 minute “leave-on” period instructedin the Clobex product label.

Compositions HA, HA-2, and CA (shown in Table 2) used a lower totalamount of cationic polymer and increased surfactant levels relative toComposition AA (shown in Table 2), but had modifications to the oilphase to improve lathering and rheology. The total oil phase level wasreduced and cetostearyl alcohol and cyclomethicone were removed. Ahigher MW oil component, coconut oil, was introduced for solubility ofHBP. The level of di-isopropyl adipate was minimized to that required tosolubilize HBP, HA and CA included and peppermint oil to help solubilizeHBP.

Example 3: In Vitro Skin Deposition and Stability of Compositions

(a) Deposition of Active Agent

The Clobex HBP Replica and Compositions AA, HA, and CA (API) wereevaluated for amount of drug deposited in vitro onto human cadaver skinmounted in 15 mm diameter Franz cells maintained at about 35° C. usingthe following simulated shampooing protocol:

Product Application

-   -   Apply target amount of 17-20 mg per cell, spread if necessary to        achieve uniform skin coverage, and leave for 15 min    -   Recover any product/drug adhering to spreading device for assay        with mobile phase    -   Add 200 μL water and mix to create lather for about 30 s    -   Dilute with additional 0.5 mL water and mix for 60 sec    -   Pour off water/product and retain for assay    -   Rinse with 1.0 mL water, recovering for assay    -   Termination of test procedures (24 hr)    -   Remove receptor fluid and retain for assay    -   Remove skin and wipe aggressively with filter paper (soaked in        mobile phase) to remove residual product    -   Extract filter paper for drug assay    -   Cut up skin and extract with mobile phase for drug assay

Assays:

-   -   Adhered drug to spreading device    -   Water/product from lathering and dilution    -   Rinse water    -   Water systems could be combined    -   Receptor fluid    -   Extract of filter paper used to remove residual product at        termination of test    -   Extract(s) of skin

Four replicates of each of the four products were evaluated.

Table 3 summarizes the amount of HBP detected on the skin surface after24 hours, which may be considered the amount of drug deposited from thecomposition during application. All three compositions had considerablyhigher HBP amounts on after 24 hours than the Clobex Replicate. Thissuggests that the approach of incorporating HBP in a dispersed oil phasein the shampoo matrix is superior in depositing HBP than the approachused in Clobex of solubilizing the drug in a surfactant matrixcontaining a relatively high level of ethanol (10%). Composition AAyielded most favorable results.

Example 4: Wear Studies

The Clobex HBP Replica and compositions AA, HA, and CA (API)formulations were evaluated for in-use properties by seven patientsusing the following instructions:

-   -   “Wet scalp and hair in shower. Dispense about one teaspoon        shampoo in palm and apply to scalp, massaging with fingers to        assure shampoo is in contact with scalp and not just hair.        Continue with showering of rest of body, leaving shampoo in        contact with scalp through (and for at least 5 minutes).    -   Add more water to shampoo on scalp and massage to create lather.        Rinse, minimizing contact of shampoo with rest of body.”

The results are shown in Table 8. Based on the compiled rankings, HA wasthe most preferred followed by CA and both were rated much higher thanthe Clobex HBP Replica. AA had a similar rating to Clobex HBP Replica.
